Question

System.ArgumentNullException: Value cannot be null - when using SetValue

Asked by: GLComputing

Trying to use the SetValue function to set data in a field via an SDK (see code below).

oppF  and oppF2 are not null because they return a field name.  I also tried those commented statements but still throw the same error. What am I doing wrong here?

I get this error:
System.ArgumentNullException: Value cannot be null.
Parameter name: format
    at System.String.Format(IFormatProvider provider, String format, Object[] args)
    at System.String.Format(String format, Object arg0, Object arg1)
    at Act.Framework.Opportunities.Opportunity.OpportunityFieldCollection.SetData(MutableEntityColumn column, Object data)
    at Act.Framework.MutableEntities.MutableEntity.FieldCollection.set_Item(String name, FieldNameType fieldNameType, Object value)

Would appreciate any suggestions to find the cause...

Act.Framework.Opportunities.OpportunityList ol = ACTFM.Opportunities.GetOpportunities(null);
 
                MutableEntityFieldDescriptor oppF = ACTFM.Opportunities.GetMutableEntityFieldDescriptor("MyCustomField1", FieldNameType.Alias);
                MutableEntityFieldDescriptor oppF2 = ACTFM.Opportunities.GetMutableEntityFieldDescriptor("MyCustomField1", FieldNameType.Alias);
                
                foreach (Act.Framework.Opportunities.Opportunity op in ol)
                {
                    MessageBox.Show(oppF.Name);
                    MessageBox.Show(oppF2.Name);
            try
                {
                    //op.Fields[oppF.Name, true] = "123123";
                    //op.OpportunityFields[oppF.Alias, FieldNameType.Alias] = "123";
 
                    oppF.SetValue(op, "123");
                    oppF2.SetValue(op, true);
 
                    //op.Fields[oppF.Name, true] = "123123";                    
                   // op.Fields["MyCustomField1", FieldNameType.Alias] = "123";
                    op.Update();
                  }
                   catch (Exception ex)
                    {
                        MessageBox.Show(ex.ToString());
                    } 
 
                 }

At which line is the error occurring?

By your statement that oppF and opPF2 are returning a name, I assume it happens in the try-block.

I would suggest setting a breakpoint on the tryblock and examine the variables when walking through the lines.

Hello,

I wonder if there's another zone you might have better luck in. This seems like an ACT issue. One would need to be familiar with their framework. Since you're enumating the oppurtunities (and thus op is not null), the only other argument is the hard-coded string, so I don't see how this error would occur. I don't know how their framework works, though, so I have to assume there's additional logic in the SetValue method that isn't happy.

 

by: djjariesPosted on 2009-10-08 at 06:32:29ID: 25525120

I've seen in the past that a wrong argument can destroy the original object. It is very possible that op becomes null. Hence my question.

The ACT Zone doesn't have anyone who knows more about ACT! than I do :-)

We're trying a couple of other tests to see if we can narrow it down

It seems it might be an ACT! issue...

The field is read Only, but the SDK is still supposed to be able to write and it does so if the field is empty, but this error happens if trying to write when the field is populated.
